In the computer world, they are the de facto standard for implementing password security. However, they can be guessed, broken or captured, which is their main disadvantage. To compensate for this weakness, we can choose two-factor authentication.
Unlike passwords, two-factor authentication (2FA) is a two-step process where you prove your identity by asking for two of three possible pieces of information, or factors: what you are, what you have, or what you know. Current implementations of two-factor authentication use something you know (passwords) and something you have or own (such as a mobile phone, email account, security token, etc.)
WordPress really offers two-factor authentication through free plugins that allow you to implement different methods of two-factor authentication , including one-time password (OTP) via SMS, phone call, one-time password via e-mail, QR code, authenticator applications , push notifications, and hardware-based security tokens such as Yubikey, SolidPass, etc.
